The cone forming part of the ram is pr ferably made of iron or steel,but any suitable material may be used. 7

It will be obvious that the ranr levels off the material in theincinerator quickly and What I claim is: e t

.1. In an incinerator having a floor, a charging door above said flooradapted to charge the; material to be burned onto the center of thefioor of the furnace chamber and a stoking ram at the center of saidfloor, in combination wlth means adapted'to raise said ram to distributethe charge over: said floor;

ing afloor, a charging door above saidfloor adapted to pile upon thefloor the material to be burned, and a ram in said floor in verticalalignmentwith said door, and the top of said ram normally completingsaid floor, in combination with means adapted to force said ram upwardto distribute over said floor the material .to be burned.

3. In an incinerator having a floor a charging door adapted to chargeonto the floor .the'material to be burned, and a ram in saidfloor, invertical alignment With said door,'said ram having acone pointingupward; the base of the cone being normally level with said floor, incombination With means adapted to raise said ram to carry the base ofthe cone above the floor; I
